            expandedNodes.add(node);
        }
    }
    // update the table then restore expanded nodes
    tablesModel_.update(// connection 
    connection, // track nodes to expand
    expandedNodes, new // table update completed, expand nodes
    Command() {

        @Override

            }
        }
    }, new // node expansion completed, restore scroll position
    Command() {

        @Override
        public void execute() {
            // delay 100ms to allow expand animation to complete
            new Timer() {

                @Override
                public void run() {
                    scrollPanel_.setVerticalScrollPosition(scrollPosition);
                }
            }.schedule(100);
        }
    });

        }
        openMap.put(getTreeNodeId(treeNode.getChildValue(i)), treeNode.isChildOpen(i));
        // This gets the child node, but doesn't change the open status (there's no other way to get the child)
        TreeNode childNode = treeNode.setChildOpen(i, treeNode.isChildOpen(i));
        getNodeOpenMap(childNode, openMap);
